Applieation filed June 13, 1919. Serial No. 303,835.

a To all whom it may concern .Be it known that I, EDWIN Gnnnnn, a citizen of the United States, residing in the borough of Manhattan, city, county, and

State of New York, have invented certain new and useful Improvements in Machines for Making stretchable Crinkled Paper, of which the following is a full, clear, and exact description. I

This invention relates to a machine for making stretchable crinkled paper of the type that is used for packing and wrapping purposes.

In the manufacture of crinkled paper it is desirable that the paper be moistened before it is placed on the receiving roll and acted upon by the doctor to form the crinklesin the paper. After the paper has received these crinkles, it must again be dried and in such a manner that the crinkles are not destroyed during the drying. The drylng process requires a considerable amount of heat and renders the rooms more or less uncomfortable.

It is an object of this invention to condition the paper while in the web for being placed upon the receiving roll so that it may be crinkled by the doctor with a minimum amount ofmoisture content. By so reducing the moisture content less heating will be required to subsequently dry the v crinkled paper. 7

Other objects of the invention will appear as the description proceeds.

In the drawings, wherein is shown a preferable embodiment of my invention, Figure l is an elevational view showing the general arrangement of parts;

Fig. 2 is a top plan view, and V Fig. 3 is a sectional view on the line 33 of Fig. 1. p i

In the drawings, wherein similar reference characters refer to similar parts throughout'the several views, 4: represents the main frame of the crinkling machine. At one end of this frame on a suitable bracket 5, the supply roll 6 of paper is carried.

A closed steam chest 7 is carried by the frame. This chest has a pair of doors 8 which may be opened to obtain access into the interior thereof. The upper regions of the steam chest have two slotted openings 9 and 10 through which the paper may he passed. Within the chest is a suitable set of guiding rollsll, which direct the paper Specification of Letters Patent.

in a tortuous path through the chamber. It is desirable that the openings 9 and 10 permit the free passage of the paper, and in orderto seal these openings the web 6 is caused to pass between the cooperating pairs of rolls 12 and 13 which are carriedby suitable framework 14 and 15. The frames 14 and 15 have rectangular openings to accommodate the rolls 12 and 13. The upper roll rests upon the paper and therefore will not permit the steam to pass outwardly from the chest. The moistened paper is drawn through the steam chest and about the rolls 11 through the rolls 18 and the slit 10 by means of a set of squeeze rolls 16 which may be adjusted by hand wheels 16, whereby the moisture on the web of paper is squeezed through its fibers, permeating and softening the same. These rolls feed the web on toward the receiving roll. The lower of these rolls is driven by belt 17 carried on the power shaft 18 which is supported on the main frame a. The shaft 18 also carries a smooth metal receiving roll 19.

' fter the web 6 has passed between the rolls 16, it is fed about a pressure-applying roll 20 which squeezes the wetted web of paper against the receiving roll, expelling any excess moisture which may remain in the pa- I per and pressing the wet paper in close adherence to the receiving roll. 21 represents the doctor which is held by suitable mechanism and acts to form the crinkles in the paper.

The amount of steam which is admitted to the box may be readily controlled by valves, not shown, in the supply line 22, and the condensed water drained away through pipe 23. Opening the doors 8 permits ac cess to the chest andso that the web of paper from the roll 6 may be started in the tortuous path about the rolls 11 in the chamber. While passing through the chamber, the pa per willabsorb moisture from the steam, and thereby become softened without being soaked in water. It will, therefore, not require so much heatin to dry the paper after it has been crinkled by the doctor.

If desired, one or more additional pairs of squeeze rolls 21 through which the paper passes may be located within the steam chest, such rolls being provided with adjusting hand wheels 24 and being driven by a belt 25 which passes around a pulley 26 on the lower roll 16 at the farther end and around a pulley 27 at the farther end of the lower roll 24. Of course, as manypairs of squeeze rolls or'other squeezing devices may be employed as circumstances require. 7

l/Vhile I have shown my invention in what I believe to be the most efiicient and desirable form,,it will be understood that various changesfmay be made without departing for soueezin into the 5a oer the moisture del b o the paper passes for moistenins POSllLGCl'llllGIGOIl by the steam.
